FWIW - I had bought this to use for my 4.0 swap into my TJ as I could not find any TJ 4.0 harnesses for sale. I determined the pin outs in the PCM connectors would match up - I matched up basically all the other connectors - determined I could make it work with some minor work - was about to use it then found a great deal on a TJ harness - so set this one aside.
